How to proxy context to different backend context in apache

apache-2.2cherrypyreverse-proxy

I'd like to configure apache so that http://my-domain.com/myapp serves a Python webapp running in CherryPy on a backend server.

Here's what's in the vhost:

    RewriteRule ^/myapp/?(.*) http://backend-server:8000/$1 [P]
    ProxyPassReverse /myapp/ http://backend-server:8000/

When I trace the request/response, I see: 

GET /myapp HTTP/1.1
Host: my-domain.com

And then: 

HTTP/1.1 303 See Other
Date: Thu, 15 Sep 2011 21:46:35 GMT
Server: CherryPy/3.1.2
Content-Type: text/html;charset=utf-8
Location: http://my-domain.com/somwhere-else/

As you can see, the CherryPy webapp sends a 303 redirect to /somewhere-else/

Any ideas why the Apache ProxyPassReverse doesn't transform the Location to http://my-domain.com/myapp/somewhere-else?

Best Answer

Your source location is /myapp, while your ProxyPassReverse is for /myapp/; context of the proxied location doesn't match, so the ProxyPassReverse doesn't apply.

Why the mod_rewrite proxy? This should accomplish the same, and have no trailing slash consistency issues:

ProxyPass /myapp http://backend-server:8000
ProxyPassReverse /myapp http://backend-server:8000
